I've got a method:

public native void doSomething(ByteBuffer in, ByteBuffer out);

Generated by javah C/C++ header of this method is:

JNIEXPORT void JNICALL Java__MyClass_doSomething (JNIEnv *, jobject, jobject, jobject, jint, jint);

How can I get a data array from jobject (that is a ByteBuffer instance) ?

ByteBuffer recycling class

Hi everyone, I'm wonder how I'd code up a ByteBuffer recycling class that can get me a ByteBuffer which is at least as big as the specified length, and which can lock up ByteBuffer objects in use to prevent their use while they are being used by my code. This would prevent re-construction of DirectByteBuffers… >>> More
